Title:
TRAFFIC REINJECTION METHOD AND PROTECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/185502
Kind Code:
A1
Abstract:
The present application relates to the field of network security, and provides a traffic reinjection method and a protection system. The present application provides a traffic reinjection mode based on SRv6. After traffic cleaning is performed by the protection system, an SRv6 SID of a router in front of a protected network is added to the cleaned traffic, so that the cleaned traffic can be guided to the router in front of the protected network by means of the SRv6 SID. In this way, each hop router through which a reinjection link passes can achieve, on the basis of an IPv6, forwarding of the cleaned traffic without requiring that each hop router on the reinjection link is upgraded, thereby reducing implementation complexity.
